Problems solved by technology

[0002] There are many kinds of load specifications of the elevator, so the suspension distance of the compensation rope of the elevator also has many situations. If only one compensation wheel is used under the pit of the shaft, it is often required that the diameter of the compensation wheel is larger, and different compensation ropes are used for hanging. The distance requires that the diameter of the compensation wheel will be different, and the tension force of the compensation wheel required by elevators with different load specifications will also be different, and the weight of the compensation wheel will also be different. The unit causes inconvenience in production management, and the cost of the very heavy compensation wheel is also very high

Abstract

The invention provides an elevator compensation rope tensioning device which comprises guide rails respectively and perpendicularly arranged on two sides of an elevator well pit and guide supports. A left wheel installation plate and a right wheel installation plate are symmetrically arranged between the two guide rails, the external outlines of the left wheel installation plate and the right wheel installation plate are in C shapes, the left wheel installation plate and the right wheel installation plate bypass a compensation rope, guide shoes are arranged on the outer side of the left wheel installation plate and the outer side of the right wheel installation plate corresponding to the guide rails, a horizontally-arranged left compensation wheel and a horizontally-arranged right compensation wheel are respectively fixed between two support legs, thread sleeves are fixed at the outer ends of the support legs, horizontally-arranged double-head telescopic screws matched with the thread sleeves to act are respectively arranged between the two thread sleeves on the same side of the left wheel installation plate and the same side of the right wheel installation plate, threads at two ends of the each double-head telescopic screw are opposite, the guide supports are respectively parallel to the double-head telescopic screws, one end of each extension spring is sleeved on the outer wall of the guide support, and the other end of each extension spring is connected with the support leg of the installation plate at the corresponding position or a connection shaft of the compensation wheel.

Description

technical field [0001] The invention relates to an elevator compensation rope tensioning device, in particular to an elevator compensation rope tensioning device capable of adapting to various compensation rope suspension distances and various compensation pulley tension requirements. Background technique [0002] There are many kinds of load specifications of the elevator, so the suspension distance of the compensation rope of the elevator also has many situations. If only one compensation wheel is used under the pit of the shaft, it is often required that the diameter of the compensation wheel is larger, and different compensation ropes are used for hanging. The distance requires that the diameter of the compensation wheel will be different, and the tension force of the compensation wheel required by elevators with different load specifications will also be different, and the weight of the compensation wheel will also be different. The unit causes inconvenience in producti...
